Coloring material 2815 55 member 26 to the rear of said stencil, and said coloring material will pass through the apertures 29 of the stencil belt and will adhere to the we I below to create a design thereon.

If an ordinary paint or coloring material were employed, it would not be possible to perform the operations of cutting and stacking the cut elements without smearing of the coloring material. For this reason, it is an important part of the method that a quick drying paint be utilized as the web of building material to which the quick drying paint is applied is usually quite hot after receiving its surfacing of interspersed mineral particles and such will help drive off the volatile solvents of the paint and thereby bring about a rapid initial set. Said paint may be a cellulose mixture, as cellulose ester in a readily volatile solvent, commercially known as Duco, which possesses the property of drying very rapidly.

Inasmuch as the apertures 29 of the stencil belt must be separated at intervals as at 30 so that portions of the belt will not fall away, the

lines of demarcation which will be applied to the web will be broken at intervals. For this reason,

the printing'roller 20 is employed, said printer having a printing plate extending around its periphery which is formed to apply coloring material to the short sections of the web which are below the portions 30 of the stencil belt.. The web will therefore leave the printing roller with continuous lines of demarcation 3i thereon. Next, the web will be severed longitudinally and transversely by the knives 23 of the cutting roller 22 to produce from each side of the web a plurality of figured elements such as are shown in Figure 4.

Each of said elements is then cut inwardly from its lower edge'as at 32 to form a slit for engagement with a lug 33. The shingles produced may be laid as shown in Figure 5 with adjacent elements in the same row having overlapping ends which are interlocked through the lugs and slits 33 and 32, and with the lower edge of one row above overlapping the upper edge of a row below,

as shown in Figure 5, to create an effect of a plurality of brick-like figures.

Although the coloring material 28 is shown as applied in the form ofa spray, it may also be applied by a soft application roll, or in any other suitable manner. It is further to be understood that the stencil may be formed to produce any type of design on the web, the brick-like design shown being merely for the purpose of illustration. All other changes and modifications are also contemplated as may come within the scope of the claims. v

I claim:

1. As an article of manufacture, a colored shingle element comprising a water resistant flexible base, a granular surface roughening material adhesively secured to said base, and a' hardened and weather-resistant colored coating secured to the exposed surface of said granular materiaLsaid coating comprising a substantially water-insoluble quick drying lacquer.

2. An ornamental shingle element comprising a base, a surface roughening material comprising mineral particles adhesively secured to said base and a colored coating comprising a hardened and weather-resistant film comprising a substantially water-insoluble quick drying coating secured to the exposed surface of said mineral particles and adhesive, said particles acting as ameans of bonding said coating to said bme.

3. its articles of manufacture flexible shingle elements each comprising a fibrous base, a bituminous layer, mineral particles interspersed and partially embedded in said layer, and a hardened weather-resistant color surfacing comprising a substantially water-insoluble quick drying film over said mineral particles, said mineral particles acting as the principal means of bond for said surface coating and said shingle elements being adapted to be stacked during manufacture without smearing their surfacing. '4. As articles of manufacture ornamented flexible shingle elements comprising mineral surfaced flbrous bases having thereon continuous colored bands' of a hardened weather-resistant coating anchored by said mineral surfacing in position, said coating comprising a substantially water insoluble quick drying lacquer.

5. As articles of manufacture ornamented flexible shingle elements comprising mineral surfaced fibrous baseshaving thereon continuous colored bands of a hardened coating anchored by and covering the exposed portions of said mineral surfacing said coating comprising a quick drying cellulosic ester lacquer.

6. As an article of manufacture, a colored shingle element comprising a water resistant flexible base, a granular surface toughening material adhesively secured to said base and partially embedded thereln, and a colored coating comprising the dried residuum of a quick drying cellulose ester lacquer over the exposed portions of said particles and anchored thereto, said granular surfacing acting as the principal means of bond for said colored coating.

7. An ornamental shingle element comprising a base, a surface roughening material comprising mineral particles adhesively secured to said base and partially embedded therein and a hardened weather resistant colored coating comprising a quick drying cellulose ester lacquer over said base and exposed mineral particles and without affecting the texture of said particles, said particles acting as a means of bonding said coating to said base.

8. As articles of manufacture flexible shingle elements each comprising a fibrous base, a bituminous layer, mineral particles interspersed and partially embedded in said layer, and a hardened weather resistant color surfacing comprising a substantially water-insoluble coating having quick drying characteristics covering the exposed portion of said particles and the bituminous layer therebetween to protect the same, said mineral particles acting as the principal means of bond for said surface coating, and said shingle elements being adapted to be stacked during manufacture without smearing their surfacing.
